user/spack: relocate default configuration. fixes #1108.

Switching to a file-based (as opposed to patch-based)
configuration will be easier for us to maintain. Note
that '/opt/spack/etc/spack/config.yaml' will override
values in '/etc/spack/config.yaml'.

Also:

  * change upstream spack.git provider; fixes spack#8,
    which gives users immediate access to our patches
    if they wish to set up a separate Spack tree
